Hi-Speed USB 2.0 Support

NOTE

Computer systems that have an unshielded cable attached to a USB port might not meet FCC Class B requirements, even if no device or a low-speed USB device isattached to the cable. Use a shielded cable that meets the requirements for a full-speed USB device.

The desktop board supports up to eight USB 2.0 ports via ICH7 (four ports routed to

the back panel and four ports routed to two internal USB 2.0 headers). USB 2.0 portsare backward compatible with USB 1.1 devices. USB 1.1 devices will function normallyat USB 1.1 speeds.

USB 2.0 support requires both an operating system and drivers that fully supportUSB 2.0 transfer rates. Disabling Hi-Speed USB in the BIOS reverts all USB 2.0 portsto USB 1.1 operation. This may be required to accommodate operating systems thatdo not support USB 2.0.




18

Enhanced IDE InterfaceThe desktop board’s IDE interface handles the exchange of information between theprocessor and peripheral devices such as hard disk drives and CD-ROM drives. Theinterface supports:

• Up to two IDE devices (such as hard drives)• ATAPI-style devices (such as CD-ROM drives)• Older PIO Mode devices• Ultra DMA-33 and ATA-66/100 protocols

Serial ATAThe desktop board supports four Serial ATA channels (3.0 Gb/s) via ICH7, connectingone device per channel.

Expandability

For system expansion, the desktop board provides the following:• One PCI Express x16 connector• One PCI Express x1 connector• Two PCI bus connectors

BIOSThe BIOS provides the Power-On Self-Test (POST), the BIOS Setup program, thePCI/PCI Express and IDE auto-configuration utilities, and the video BIOS. The BIOS isstored in a Serial Peripheral Interface (SPI) Flash device.

The BIOS can be updated by following the instructions on page 58 in Chapter 3.

Serial ATA and IDE Auto ConfigurationIf you install a Serial ATA or IDE device (such as a hard drive) in your computer, theauto-configuration utility in the BIOS automatically detects and configures the devicefor your computer. You do not need to run the BIOS Setup program after installing aSerial ATA or IDE device. You can override the auto-configuration options byspecifying manual configuration in the BIOS Setup program.




19

PCI and PCI Express* Auto ConfigurationIf you install a PCI/PCI Express add-in card in your computer, the PCI/PCI Expressauto-configuration utility in the BIOS automatically detects and configures theresources (IRQs, DMA channels, and I/O space) for that add-in card. You do not needto run the BIOS Setup program after you install a PCI/PCI Express add-in card.

Security PasswordsThe BIOS includes security features that restrict whether the BIOS Setup program canbe accessed and who can boot the computer. A supervisor password and a userpassword can be set for the BIOS Setup and for booting the computer, with thefollowing restrictions:

• The supervisor password gives unrestricted access to view and change all Setupoptions. If only the supervisor password is set, pressing <Enter> at the passwordprompt of Setup gives the user restricted access to Setup.

• If both the supervisor and user passwords are set, you must enter either thesupervisor password or the user password to access Setup. Setup options are then

available for viewing and changing depending on whether the supervisor or userpassword was entered.

• Setting a user password restricts who can boot the computer. The passwordprompt is displayed before the computer is booted. If only the supervisorpassword is set, the computer boots without asking for a password. If bothpasswords are set, you can enter either password to boot the computer.

Related Links:

For instructions on resetting the password, see Clearing Passwords on page 52.

Hardware Management Features

The hardware management features of Desktop Board D946GZAB enable the board tobe compatible with the Wired for Management (WfM) specification. The board hasseveral hardware management features including the following:

• Fan speed monitoring and control• Thermal and voltage monitoring• Chassis intrusion detection

Hardware Monitoring and Fan Speed ControlThe features of the hardware monitoring and fan speed control include:

• Monitoring of power supply voltages to detect levels above and below acceptable

values• Intel® Precision Cooling Technology• Thermal sensors in the processor, GMCH, and ICH7 plus an onboard remote sensor• Thermally monitored closed-loop fan control, for all onboard fans, that can adjust

fan speed or switch the fans off as needed






21

Fan HeadersThe function/operation of the fans is as follows:

• The fans are on when the computer is in the ACPI S0 state.• The fans are off when the computer is in the ACPI S3, S4, or S5 state.• Each fan header is wired to a tachometer input of the hardware monitoring and

control device.• All fan headers support closed-loop fan control that can adjust the fan speed or

switch the fan on or off as needed.• All fan headers have a +12 V dc connection.

The desktop board has a 4-pin processor fan header and two 3-pin chassis fanheaders.

LAN Wake Capabilities

CAUTION

For LAN wake capabilities, the 5 V standby line for the power supply must be capableof delivering adequate +5 V standby current. Failure to provide adequate standby current when using this feature can damage the power supply.

LAN wakeup capabilities enable remote wake-up of the computer through a network.The LAN subsystem monitors network traffic and upon detecting a Magic Packet*frame, it asserts a wake-up signal that powers up the computer.

Instantly Available PC Technology

CAUTIONS

For Instantly Available PC technology, the 5 V standby line for the power supply must be capable of delivering adequate +5 V standby current. Failure to provide adequatestandby current when using this feature can damage the power supply and/or effect

ACPI S3 sleep state functionality.

Power supplies used with this desktop board must be able to provide enough standby current to support the standard Instantly Available (ACPI S3 sleep state) configuration.If the standby current necessary to support multiple wake events from the PCI and/or USB buses exceeds power supply capacity, the desktop board may lose register settings stored in memory.

Instantly Available PC technology enables the board to enter the ACPI S3 (Suspend-to-

RAM) sleep state. While in the S3 sleep state, the computer will appear to be off. If the computer has a dual-colored power LED on the front panel, the sleep state isindicated by the LED turning amber. When signaled by a wake-up device or event, thecomputer quickly returns to its last known awake state.






23

Wake from PS/2 Keyboard/MousePS/2 keyboard/mouse activity wakes the computer from an ACPI S3 state.

PME# Signal Wake-up Support

When the PME# signal on the PCI bus is asserted, the computer wakes from anACPI S3, S4, or S5 state.

WAKE# Signal Wake-up SupportWhen the WAKE# signal on the PCI Express bus is asserted, the computer wakes froman ACPI S2, S3, S4, or S5 state.

SpeakerA speaker is mounted on the desktop board. The speaker provides audible error code(beep code) information during the Power-On Self-Test (POST).

BatteryA battery on the desktop board keeps the values in CMOS RAM and the clock currentwhen the computer is turned off. Go to page 54 for instructions on how to replace thebattery.

Real-Time ClockThe desktop board has a time-of-day clock and 100-year calendar. The battery on thedesktop board keeps the clock current when the computer is turned off.

Updating the BIOS with the ISO Image BIOSUpdate File or the Iflash Memory UpdateUtility

You can use the information in this section to update the BIOS using either the IflashMemory Update Utility or the ISO Image BIOS update file.

Obtaining the BIOS Update FileYou can update to a new version of the BIOS by using the ISO Image BIOS update file(recommended), or Iflash BIOS update file.

The ISO Image BIOS update file is a standardized image of a bootable CD-ROM thatcan be used to create a bootable CD that will update the BIOS.

The IFlash BIOS update file is a compressed file that contains the files you need toupdate the BIOS. The IFlash BIOS update file contains:

• New BIOS file• Intel® Integrator Toolkit Configuration File (optional)• Intel Flash Memory Update Utility

You can obtain either of these files through your computer supplier or by navigating tothe Desktop Board D946GZAB page on the Intel World Wide Web site at:


Navigate to the D946GZAB page, click “[view] Latest BIOS updates,” and select the ISOImage BIOS Update or Iflash BIOS Update utility file.

Updating the BIOS with the ISO Image BIOS Update

FileThe ISO Image BIOS update allows for the update of an Intel® Desktop Board BIOS tothe latest production release regardless of the operating system installed on thecomputer's hard drive and without the need to remove the BIOS configuration jumper.It requires a blank CD-R, a read/writeable CD drive, and software capable of uncompressing and writing the ISO image file to CD.

The image uses ISOLINUX* bootloader and automatically launches a script to upgradethe BIOS via the Iflash utility.

CAUTION

Do not interrupt the process or the system may not function properly.








62

CAUTION

Do not interrupt the process or the system may not function properly.

1. Uncompress the BIOS update file and copy the .BIO file, IFLASH.EXE, and .ITK file(optional) to a bootable USB flash drive or other bootable USB media.

2. Configure the BIOS or use the F10 option during POST to boot to the USB device.3. Manually run the IFLASH.EXE file from the USB device and manually update the

BIOS.

Recovering the BIOSIt is unlikely that anything will interrupt the BIOS update; however, if an interruptionoccurs, the BIOS could be damaged. Due to BIOS size and recovery requirements, aCD-R with the .BIO file in the root directory will be required. For more informationabout recovering the BIOS for desktop board D946GZAB, go to:
